On semi-auto matic pistols, a lever that mechanically lowers the hammer without firing the gun.
Also known as a Flash Hider. A muzzle attachment intended to reduce visible muzzle flash caused by the burning propellant.
Flash reducers lessen glare as seen by the shooter, but do not hide the flash from other observers to the front or side of the firearm.
In the rifling of a bore, the uncut portions of the barrel's inner surface left after the rifling grooves have been cut into the metal. In other words, the raised portion of rifling.
A hammerless single shot action type whereby a breech-block, hinged at the upper rear, operated by an underlever, tilts downward to expose the chamber.
The spotter is a helper who gives the shooter guidance on how to hit a particular target.
In some cases the spotter may just report the location of the bullet impact. In other cases they may judge the speed and direction of
the wind, determine the range, and give the shooter the settings to be used on the sights.
A game of competitive clay pigeon shooting on a formally designed layout. In plan view, one launching machine is located 16 yards in front of a straight line,
firing rising targets perpendicular to and away from that line. Five competitors shoot five individual targets at each of five stations along that line.
Although each target is presented at slightly randomized vectors, trap emphasizes generally a single type of shot, outgoing and rising,
and targets are broken at generally longer ranges than Skeet.
To prepare or charge a muzzle loader for firing.
To explode with great violence. It is generally associated with high explosives e.g. TNT, dynamite, etc., and not with the relatively slow-burning smokeless gunpowders that are classed as propellants.
A rebound, bounce or skip off a surface, particularly in the case of a projectile.
Two firearms that are manufactured identical in every way and are sequentially serial numbered and are sold as a set.
The most common type of matched pair guns are cowboy style revolvers for a couple of reasons, both guns will feel exactly the same in the hands and they make the set more collectable.

Pitch is measured by resting the gun with its butt flat on a floor, the top of the receiver against a wall and its muzzle pointing up.
The distance of the muzzle from the wall is the gun's pitch down.
A bullet design featuring a conical extended nose, with a flat point, and a sharp edged shoulder that serves to cut a full diameter hole in the target.

The part in the breech mechanism that locks the action against the firing of the cartridge.

Also spelled blueing.
A passivation process in which steel is partially protected against rust, and is named after the blue-black appearance of the resulting protective finish.
True gun bluing is an electrochemical conversion coating resulting from an oxidizing chemical reaction with iron on the surface selectively forming magnetite
(Fe3O4), the black oxide of iron, which occupies the same volume as metallic iron. Bluing is most commonly used by gun manufacturers, gunsmiths and gun
owners to improve the cosmetic appearance of, and provide a measure of corrosion resistance to, their firearms.
A concave, semi-cylindrical surface cut into the forward lump of a barrel set of a break-open firearm which revolves about the hinge-pin when the gun is opened.
A soft appendage, usually of some kind of rubber, often fitted to the butt end of a shoulder-mounted firearm to reduce the sensation of recoil.
A recoil pad has the additional benefit of being less vulnerable to damage than a checkered wood butt or a brittle horn or plastic buttplate.
